How to unlock an iPhone from it's carrier?

I've recently got an iPhone from someone that was former on Sprints network. I'm trying to get the iPhone unlock so I can work on Virgin Mobile's carrier. I've spoke to them and they to be I would have to unlock the phone somehow and the company can take carry of the rest from downhill. Does anyone have or know I can unlock this phone without Jail breaking the phone or paying money to do this?

I do, it's pretty easy.

Did you try turning it off and back on again?

Unlocking an iPhone allows you to use SIM cards from local wireless carriers when traveling abroad, which are usually cheaper than paying for international coverage from AT&T. You can also use the phone on other GSM carriers in the United States, such as T-Mobile, although data speeds will be slower, and you can't use an unlocked AT&T iPhone on Verizon Wireless or Sprint.

NO, there's ABSOLUTLEY NO Way to use any phone from any other carrier on Virgin Mobile USA's network.

The ONLY phones that will work on Virgin Mobile USA's network are VIRGIN MOBILE USA PHONES!

They don't use SIM cards. You can get an iPhone 4S for Virgin Mobile USA for $449 and $30 a month but that iPhone on Virgin Mobile USA will be locked on Virgin's network forever.

They don't flash phones at all. I encourage you, go to their Facebook page and ask them or call them up! They'll tell you the same exact thing I just said - I guarantee it! I PROMISE YOU I'M RIGHT!

  • Will updating my iphone 4 to ios 6 will disable its carrier unlock? My Iphone 4 is currently running on ios 4.3.3 and I wish to update it to the new os (the ios 6), but don't want to lose its carrier unlock. I don't actually know if its an official factory unlock or what but what I know is that the Iphone is not jailbreaked (So If I assume right, Is it really a factory unlock and won't be affected by any update?). Please give the answers not involving a jailbreak.
